n-Code ads w/ the Williams Sisters

Maybe I'm wrong about this, but am I the only one who thinks it's a little odd that Venus and Serena are in the new N-Code advertisements when, at Wimbledon, they're still using old Powerholes racquets(I think) painted as H4s and H6s, respectively (Maybe they are actually the new H series, I'm not too sure about that, but that's not the point). I understand Federer, because his is, at least, painted like an n-Code, but the Williams haven't even made the effort to change the paint of theres.
